PERCOLATOR.

SPECIFICATION forming part of Letters Patent No. 764,750, dated July 12,1904.

Application filed July 16,1903. Serial No. 165,880.

1'0 all whom it may concern.-

Be it known that I, l/VILLIAM WV. MUNGER, a citizen of the UnitedStates, residing at Three Rivers, in the county of St. Joseph and Stateof Michigan, have invented new and useful Improvements in Processes ofExtracting the Medical Properties from Drugs, of which the following isa specification.

The invention relates to an apparatus for extracting the medicinalproperties from drugs, and has for its object to render the process moreexpeditious and considerably cheaper without loss of the drug oralcohol.

Figure 1 is an elevation of the percolator partially in sections. Fig. 2is a detail view of the disk.

A. This is a container for the menstruum, made of copper, tin, or othermetal.

B. This is a stop-cock to regulate the flow of menstruum.

C. This is a container for the drug (also made of copper, tin, or othermetal) having an inverted-funnel-shaped top and also a funnel-shapedbottom. The latter is removed at the point D for filling the percolator.

E. This is a perforated disk against which the drug is packed. This isalso a perforated disk attached to and a part of the rod F.

F. This is a rod held in place by the thumbscrew H.

G. This is a bar held in place by slipping into notches at each end,having a hole in the center through which the rod F passes.

H. This is a thumb-screw by which rod F is held in place, permitting ofits being raised or lowered.

I. This shows part C with funnel-shaped bottom removed, looking straightinto it.

J. This is several feet of rubber tubingconnecting parts A and (J.

In using the percolator, part C is inverted. The funnel-shaped bottom isremoved and also parts F and Gr. Disk E is put in place and covered witha piece of moist canton-flannel (No model.)

cut to fit inside of percolator. The drug being ground for percolationand thoroughly moistened with the proper menstruum is then carefullypacked in part C against disk E. The drug is then covered with anotherpiece of moist canton-flannel. Parts F and G are then put in place, partF being pressed firmly against the drug and held in position bythumbscrew H. The funnel-shaped bottom is then put on, fitting over theend of part C. Part C is then inverted and ready for operation, as shownin drawings. It may rest on a filterrack or other apparatus. Part A isthen filled with the proper menstruum and attached to part 0 with rubbertubing J. PartA is suspended from the ceiling with a pulley and cord,and the menstruum is forced down through the drug, coming out at the endof the funnel-shaped bottom. The proper pressure is obtained by raisingor lowering the menstruum-container A.

In the use of this percolator no alcohol can evaporate. All the strengthis obtained from the drug and an even steady pressure is had at alltimes, and the pressure can be regulated to suit all conditions, so thatthe percolate or extract is not forced through too fast or too slow.

What I claim is- A percolator consisting of the container for the drughaving an inverted-funnel-shaped top and a funnel-shaped bottom, andprovided with a perforated disk E against which the drug is packed; alower disk supported on rod F and supported in place by bar G andWVILLIAM W. MUNGER.
